SPECIFICATION forming part of Letters Patent No. 397,075, dated January 29, 1889.

Application filed October ll, 1888. Serial No. 287,838. (No model.)

To all whom t may concern.-

Beit known that I, WILLIAM H. FULLER, a citizen of the United States of America, residing at Bladen, in the county of lVebster and State of Nebraska, have invented certain new and useful Improvements in (lultivators, of which the following is a specication, reference being had therein to the accompanyin g drawings.

This invention pertains to certain new and useful improvements in cultivators, and it comprises the details of construction, combination, and arrangement of parts, substantially as hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a plan view of my improved cultiva-tor. Fig. 2 is a side view thereof. Fig. S is a cross-sec` tion on the line oc m, Fig. l. Fig. I is a detail perspective view.

This invention relates to cultivators.

Referringl to the drawings, A designates the sled or culti vater frame, composed of two runners, a d, connected together by inclined transverse bars a c. The runners are rendered adjustable by means of nutted bolts e2 o2, passed through apertures thereof an d through slots a3 as of bars c. The upper ends of these bolts are passed through apertured blocks ai, whereon bear the washers against which the nuts rest. rlhe runners are preferably provided on their under surfaces with steel plates u, and the same protect the heads of the rearmost bolts, o?. The bars o a are connect-ed together by-a central bar, l, whereon is mounted the drivers seat l).

(l is a shield composed, preferably, of a piece of sheet metal, and is bent into an approximately U shape. 'lhe same is pivotally connected by nutted bolts b to the Ainner sides of runners`F a c, and is held in a rearwardly-inclined position by means of a strap or iron bar, b2, connected thereto at its outer end, and to the bar I3 by means of a screw, b3, passed through a slot, Z1", in said strap or bar. By this means the shield is rendered adjustable. To the front cross-bar, a', are connected two outwardly-projecting knives, I) I), for cutting big weeds, and to the under edges of runners a are secured two more knives, d d, for cutting weeds at or near their roots.

E E are two cultivator-shovels, preferably curved or bent in the manner shown, and their drag-bars e e are suitably bent and their forwardright angular ends e are inserted in suitable aperti'ires in blocks c2, secured to runners a. These drag-bars rest upon short blocks e3 c3, attached to the rear cross-band.

To cross-bar a are connected inclined rearwardly-projeeting bars F I `,'adjustably held by nutted bolts ff, passed through bar a and slots f j" of said bars F. To these bars are connected adjustable brace-plates f2, through slots f of which screws f'l are passed and screwed into bar d. Curved leveling plates or arms G G are connected by nutted bolts g g to each bar F and project at their outer ends toward the center of t-he cultivator.

It will be understood that the cultivatorshovels plow the ground on either side of the row of corn over which the shield C passes, said shield being adjustable for dilierentheight corn, and that the leveling plates or arms level the soil between the rows of corn.

By making the shield C of inverted-U shape and securing the inner end thereof to each runner u., the same permits of the adjustment of said runners the desired extent, since it will readily expand, as is obvious.

I claim as my inventionl. 'lhe combination of thc adjustable runners, the front and rear cross-bars having slots, the nutted bolts a2, the shield of approximately U shape, the nutted bolts b', sccuring the same to said runners, the strap or bar secured at its rear end to said shield and having a slot in .its forward end, and the nutted bolt Z13, substantially as set forth.

L. The combination, with the adjustable runners, the slotted cross-bars, and the shield, of the inclined cross-bars, the inclined rearwardly-proj ecti ng bars h avi ngslots, the nutted bolts passed therethrough, the brace-plates f2, having slotted ends, the screws f1, and the .leveling plates or arms G, substantially as set forth.

In testimoi-iy whereof I affix my signature in presence of two witnesses.
